Background: Epulides, tumors of periodontal origin, are commonly reported in dogs and infrequently in cats. But its documentation among wild animals is scarce. Retrospective study of the available literature did not find any report of epulis in sloth bears, though dental pathology is common in captive sloth bears. The present study depicts the details about an incidence of bilateral epulides in a captive sloth bear of Nandankanan Zoological Park, Bhubaneswar, India and its successful surgical management.Methods: A male sloth bear aged about 15 years, developed bilateral swellings at the upper jaw, protruding out of the oral cavity, impeding with its normal feeding and drinking. Close physical examination under general anaesthesia revealed that the swellings are bilateral epulides at the upper jaw involving canines of both sides. The epulides were surgically excised, histopathology of the excised mass was conducted and a course of antibiotic treatment was followed.Result: The epulides were found to be of fibromatous and ossifying type. In the present case, there was no recurrence of epulides at the surgical site after their excision and the procedure proved curative. This work is a complementary contribution to the dental pathology study of sloth bears in captivity.

AbstractBased on morphometric findings and polymerase chain reaction amplification of internal transcribed spacer regions (ITSs), the worms and eggs retrieved from sloth bear (Melursus ursinus) kept at Mahendra Mohan Choudhury Zoological Park, Chhatbir (Punjab, India) were delineated as Baylisascaris transfuga. Therapeutic intervention with fenbendazole à 10 mg/kg body weight for three consecutive days, associated with complete disinfection of the enclosures, proved to be effective for the first few days with the reduction of eggs per gram (EPG) of faeces from 2800 (zero day) to 400 (14.28 %), 700 (25 %) and 800 (28.57 %) on days 1, 4 and 7 post treatments, respectively. The intensity of EPG increased to 2400 (85.71 %) on day 21 post treatment with respect to day zero. A modified schedule with fenbendazole à 15 mg/kg body weight for first three days followed by 10 mg/kg body weight for next three days proved to be effective thus indicating the development of resistance. The study places on record the molecular characterisation of B. transfuga from sloth bears and development of resistance against fenbendazole.

Captive breeding programmes are increasingly relied upon for threatened species management. Changes in morphology can occur in captivity, often with unknown consequences for reintroductions. Few studies have examined the morphological changes that occur in captive animals compared with wild animals. Further, the effect of multiple generations being maintained in captivity, and the potential effects of captivity on sexual dimorphism remain poorly understood. We compared external and internal morphology of captive and wild animals using house mouse ( Mus musculus ) as a model species. In addition, we looked at morphology across two captive generations, and compared morphology between sexes. We found no statistically significant differences in external morphology, but after one generation in captivity there was evidence for a shift in the internal morphology of captive-reared mice; captive-reared mice (two generations bred) had lighter combined kidney and spleen masses compared with wild-caught mice. Sexual dimorphism was maintained in captivity. Our findings demonstrate that captive breeding can alter internal morphology. Given that these morphological changes may impact organismal functioning and viability following release, further investigation is warranted. If the morphological change is shown to be maladaptive, these changes would have significant implications for captive-source populations that are used for reintroduction, including reduced survivorship.

Playback experiments have proved to be a useful tool to investigate the extent to which wild animals understand numerical concepts and the factors that play into their decisions to respond to different numbers of vocalizing conspecifics. In particular, playback experiments have broadened our understanding of the cognitive abilities of historically understudied species that are challenging to test in the traditional laboratory, such as members of the Order Carnivora. Additionally, playback experiments allow us to assess the importance of numerical information versus other ecologically important variables when animals are making adaptive decisions in their natural habitats. Here, we begin by reviewing what we know about quantity discrimination in carnivores from studies conducted in captivity. We then review a series of playback experiments conducted with wild social carnivores, including African lions, spotted hyenas and wolves, which demonstrate that these animals can assess the number of conspecifics calling and respond based on numerical advantage. We discuss how the wild studies complement those conducted in captivity and allow us to gain insights into why wild animals may not always respond based solely on differences in quantity. We then consider the key roles that individual discrimination and cross-modal recognition play in the ability of animals to assess the number of conspecifics vocalizing nearby. Finally, we explore new directions for future research in this area, highlighting in particular the need for further work on the cognitive basis of numerical assessment skills and experimental paradigms that can be effective in both captive and wild settings.

Oral cancer is one of a major health problem in some parts of the world especially in the developing countries. Oral cancer is the sixth most common cancer in the world whereas in India it is one of the most prevalent cancer. Oral cavity lesions are usually asymptomatic. Accurate diagnosis of the lesion is the first step for the proper management of patients and histopathology is considered as the gold standard. The objective is to study the different patterns of oral cavity lesions seen in a tertiary care hospital of Jammu: One year retrospective study. Post graduate department of pathology.: It was a retrospective study carried out in a tertiary care centre for a period of one year from March 2020 to Feb 2021. 148 cases of oral cavity lesions were included in this study. The parameters that were included in the study were sociodemographic data, site of the lesion, clinical features and histological diagnosis. Data collected was analysed.148 cases of oral lesions were identified during the period of study. The age of patients varied from 5 to 78years and Male to Female ratio was 2.2:1. Buccal mucosa (30%) was the most common site involved which was followed by tonsil (19%). Out of 148 cases 70 cases were malignant, 10 cases pre malignant and 21 cases were benign. Squamous cell carcinoma (33.7%) was the most common lesion present in our study. Oral cavity lesions have a vast spectrum of diseases which range from tumour like lesions to benign and malignant tumours. Our study concluded that squamous cell carcinoma was the most common malignant lesion of oral cavity. Histological typing of the lesion is important for confirmation of malignancy and it is essential for the proper management of the patient.

Mucosal Lesions

Introduction: Oral mucosa can be affected by a variety of soft tissue lesions and conditions. Benign as well as malignant lesions of oral cavity are common. Squamous cell carcinoma is one of the commonest malignancies. The present retrospective study was undertaken to study the prevalence of various oral mucosal lesions in a tertiary care dental hospital of Kathmandu. Methods: This retrospective study was carried out in the Department of Oral and Maxillofacial Pathology at Kantipur Dental College and Teaching hospital from January 2015 to January 2017. The study included biopsy specimen from the oral cavity. The parameters included in the study were age, gender, site of the lesion and histopathological diagnosis. The data collected was statistically analyzed. Results: A total of 111 biopsy cases were included in the present study. Out of which, there was 16 (14.4%) cases of non neoplastic and 16 (14.4%) cases of benign pathology. The oral cavity lesions were commonly seen in age range between 6-74 years where males 59 (53.2%) were mostly affected. The most common site for oral lesion was buccal mucosa 23 (20.7%) and anterior gingiva 23 (20.7%). 15 (13.5%) cases of oral squamous cell carcinoma were seen as the predominant malignancy affecting in the vestibular region 8 (7.2%). Conclusions: The present study shows benign as well as the non neoplastic lesions were more prevalent in oral mucosa with the buccal mucosa and anterior gingiva as the commonest site of occurrence. Keywords: Benign; Malignant; Non neoplastic; Oral mucosal lesion.
